Improved Fixed-Parameter Algorithms for Two Feedback Set Problems
Abstract. Settling a ten years open question, we show that the NPcomplete Feedback Vertex Set problem is deterministically solvable in O(ck ·m) time, where m denotes the number of...

Linear Programming Based Approximation Algorithms for Feedback Set Problems in Bipartite Tournaments
We consider the feedback vertex set and feedback arc set problems in bipartite tournaments. We improve on recent results by giving a 2-approximation algorithm for the feedback vert...

Fixed-Parameter Tractability Results for Feedback Set Problems in Tournaments
Complementing recent progress on classical complexity and polynomial-time approximability of feedback set problems in (bipartite) tournaments, we extend and partially improve fixed...
